Membrane Bioreactor Processes to Meet Todays and Future Municipal Sewage Treatment Requirements?

The Membrane Bioreactor (MBR) technology is evaluated concerning central municipal sewage treatment aspects including nutrient removal, removal of micropollutants (MP) and emissions of greenhouse gases (GHG). Pilot-scale experiments in preparation for the world largest MBR process in Stockholm, Sweden show that Targeted effluent qualities could be achieved under various loads, Lower direct GHG emissions from the treatment compared to traditional treatment processes were observed, The investigated MBR process provided an efficient removal of microplastics and bacteria, and If combined with additional complementary treatment an effective removal of pharmaceutical residues and other micropollutants.
